This is one and maybe the ONLY area where I have some "consolation prize" hope if there is a Mitt nomination.
The co-chair of Mitt's judge-picking committee is Robert Bork.
Now, it is possible that Mitt is just using Bork (who, I must take as a given, will ONLY recommend Scalia-types, never Souters or worse).
By "using Bork," I mean it is possible that President Mitt (...gulp!) will ask Bork, "So, Bob, who's your pick for this SCOTUS vacancy? Oh? Strong conservative? Nahh, I don't want a Senate fight. Thanks, but I'll pick [Souter II, etc.]."
Still, bottom line, it is at least SOMEthing that Bork is on board there. If nothing else, Bork could threaten to resign in a public huff if Romney does something like what I'm fearing. Sometimes "wets" need a little pushing to be kept in line, e.g., from Miers to Alito.
